Latest Patents

Ko-Wei Lang's most recent inventions reflect his commitment to improving functionality in mechanical applications.

1. **Positive Displacement Micropump**: This invention introduces a pump design featuring a series of chambers arranged in a stack. The unique aspect of this micropump is its use of electrodeformable material which enables a diaphragm to deform and modify the volume within the chambers. The architecture of the pump is cleverly designed such that the deformation of a diaphragm to increase the volume in one chamber concurrently decreases the volume in an adjacent chamber. Furthermore, in various embodiments, these stacks can be combined with additional stacks to enhance head pressure in multiple stages, thereby optimizing pump performance.

2. **Adjustable Gap Hydrostatic Element**: This invention pertains to adjustable gap hydrostatic bearings and seals, which incorporate adjustable gaps to address issues such as wear, thermal expansion, journal speed, and radial deflection. The mechanism includes a housing that is situated adjacent to a journal, containing annular electrodeformable material. By applying voltage, this material can expand or contract radially, allowing for precise adjustment of the gap between the liner material and the journal, leading to enhanced operational efficiency.
